MIL went away on holiday, and said she wanted to cook a roast for us on Sunday when she came back. My partner phoned her and said not to worry about cooking us a roast as the weather was so hot and asked if we could bring some food around to do a bbq instead. She agreed.
Anyway, she phoned us on Saturday and said she had invited 11 of her friends around. We were under the impression it was just the family and thar it would be chilled. When she invites to many people over her friends get very drunk and she knows no interest in her grandson. So we told her we wouldn’t be going as we didn’t realise there would be so many people.
She was very offended by this but didn’t listen to our side of how we feel. Since then she’s been sending us nasty texts telling us we are antisocial and have no friends etc.
Are we being unreasonable for not going to something that we thought would just be a small family get to gather ?
